我正在使用以下代码在Android中拨打电话,但它给了我安全例外,请帮助。

 posted_by = "111-333-222-4";

 String uri = "tel:" + posted_by.trim() ;
 Intent intent = new Intent(Intent.ACTION_CALL);
 intent.setData(Uri.parse(uri));
 startActivity(intent);

权限

 <uses-permission android:name="android.permission.CALL_PHONE" />

从拨号器调用(不需要权限):

   fun callFromDailer(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_DIAL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

从应用程序直接呼叫(需要权限):

  fun callDirect(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_CALL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: SecurityException) {
            Toast.makeText(mContext, "Need call permission", Toast.LENGTH_LONG).show()
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

许可:

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

其他回答

重要提示:

如果你使用Intent。ACTION_CALL必须增加CALL_PHONE权限。

如果你不想让你的应用在没有SIM卡或没有GSM的平板电脑上显示谷歌播放,这是可以的。

在活动中:

            Intent callIntent = new Intent(Intent.ACTION_CALL);
            callIntent.setData(Uri.parse("tel:" + Constants.CALL_CENTER_NUMBER));
            startActivity(callIntent);

清单:

<uses-permission android:name="android.permission.CALL_PHONE" />

因此,如果它不是应用程序的关键功能,尽量避免添加CALL_PHONE权限。

其他解决方案:

是在屏幕上显示手机应用程序,用户只需要点击呼叫按钮:

            Intent dialIntent = new Intent(Intent.ACTION_DIAL);
            dialIntent.setData(Uri.parse("tel:" + Constants.CALL_CENTER_NUMBER));
            startActivity(dialIntent);

这样做不需要许可。

// Java
String mobileNumber = "99XXXXXXXX";
Intent intent = new Intent();
intent.setAction(Intent.ACTION_DIAL); // Action for what intent called for
intent.setData(Uri.parse("tel: " + mobileNumber)); // Data with intent respective action on intent
startActivity(intent);

// Kotlin
val mobileNumber = "99XXXXXXXX"
val intent = Intent()
intent.action = Intent.ACTION_DIAL // Action for what intent called for
intent.data = Uri.parse("tel: $mobileNumber") // Data with intent respective action on intent
startActivity(intent)

在Kotlin中使用此代码

fun makeCall(context: Context, mob: String) {
        try {
            val intent = Intent(Intent.ACTION_DIAL)

            intent.data = Uri.parse("tel:$mob")
            context.startActivity(intent)
        } catch (e: java.lang.Exception) {
            Toast.makeText(context,
                "Unable to call at this time", Toast.LENGTH_SHORT).show()
        }
    }

更优雅的选择:

String phone = "+34666777888";
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.fromParts("tel", phone, null));
startActivity(intent);

你可以使用Intent。ACTION_DIAL代替Intent.ACTION_CALL。这将显示已输入号码的拨号器,但允许用户决定是否实际拨打电话。ACTION_DIAL不需要CALL_PHONE权限。
